This wall totally fell down in a pile of stone blocks, less than two years after it was constructed by Charmichael Landscape Design. About 1 metre high, 30 feet long, on a roughly 1:2 slope. A first call was made when it started to lean over. The call was returned by a woman who said that someone would call me or come by to see it. That was 10 days ago. Nobody has contacted me at all. Now it has totally failed into a pile of stone blocks and we have called them again - and left several messages.
